Description

Technical Field

[0001] This application relates to the field of pig unloading and conveying technology, and in particular to a pig transport device for slaughterhouses. Background Technology

[0002] After pigs are sold at the farm, they are usually transported to the slaughterhouse by truck. During transportation, the pigs are loaded into the truck bed. After the pigs enter the slaughterhouse, they are guided by designated personnel to the unloading area. Then, the truck and the environment inside the truck are disinfected to ensure that no pathogens are spread. Then, the staff transfer the pigs from the truck bed to the unloading area to unload the pigs.

[0003] Traditional pig transportation often involves constructing a ramp between the truck bed and the unloading area. The pigs are then manually herded out of the truck bed and onto the ramp to reach the unloading area. However, because pigs are naturally timid, this herding process can be very stressful, causing them to panic and develop a strong stress response. This can lead to them backing away or running around wildly inside the truck bed. Furthermore, pigs raised in farms, lacking this training, may huddle together and refuse to walk on the ramp due to fear. This phenomenon not only increases the difficulty of unloading pigs, leading to low unloading efficiency, time and labor consumption, and affecting the rhythm of the slaughtering line, but also makes pigs prone to abrasions and falls after being frightened. When the stress reaction of pigs is severe, PSE meat may also appear [PSE meat refers to the characteristics of the muscle of pigs after slaughter, which is pale in color, soft in texture and exudative on the surface. It is the main manifestation of inferior meat], thus affecting the quality and appearance of pork after slaughter.

[0004] Therefore, we propose a pig transport device for slaughterhouses to solve the above problems. Summary of the Invention

[0005] To address the problems existing in the prior art, the purpose of this application is to guide live pigs to actively walk out of the truck compartment and automatically transfer them to the unloading area during unloading, preventing live pigs from backing away, running around, or crowding together during unloading, reducing stress response in live pigs, improving unloading efficiency and pork quality, and providing a live pig transportation device for slaughterhouses compared to the prior art.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution.

[0007] A pig transport device for slaughterhouses includes a mounting platform and casters at the bottom of the mounting platform. A lifting conveyor is provided above the mounting platform. The lifting conveyor includes a hydraulic cylinder, a lifting platform, a support, a drive roller, a servo motor, a steering roller, a clamping roller, a driven roller, and a conveyor belt.

[0015] Furthermore, the outer diameter of the connecting ring is smaller than the outer diameter of the steering roller and the driven roller, and both the first support plate and the second support plate are located inside the conveyor belt.

[0016] Furthermore, a guardrail 1 is fixedly installed on the lifting platform, and a guardrail 2 is fixedly installed on the support plate 2. Both guardrail 1 and guardrail 2 are located on both sides of the conveyor belt.

[0018] The mounting bracket is hung on guardrail one. The guide box is fixedly connected to the end of the mounting bracket near the inner side of guardrail one. The partition plate is fixedly connected inside the guide box. The air outlet plate is fixedly connected to the end of the guide box near guardrail one.

Magnetic sheet one and magnetic sheet two attract each other on their adjacent sides. The cover plate is rotatably connected to one end of the feeding port via a hinge. The handle is fixedly connected to the top of the cover plate.

[0019] Furthermore, both the partition plate and the air outlet plate are filter plates, and odorant particles are filled between the partition plate and the air outlet plate.

[0020] Furthermore, the second guardrail is equipped with a dispersing component, which includes a mounting plate, an infrared sensor, and a buzzer.

[0021] The mounting plate is fixedly connected to guardrail two. The infrared sensor and the buzzer are both installed on the side of the mounting plate near the conveyor belt. The mounting plate is equipped with power supply two and switch two. The infrared sensor and the buzzer are electrically connected to power supply two and switch two. The infrared sensor is controlled by the processor and the buzzer.

[0022] Compared to existing technologies, the advantages of this application are:

[0023] (1) By setting up lifting conveyor components, the hydraulic cylinder drives the lifting platform to move up and down, thereby driving the active roller, steering roller, clamping roller and conveyor belt to move up and down, so that the conveyor belt is level with the exit of the car. At this time, the height of the horizontal section of the conveyor belt changes, which will drive the slider to slide in the slide, so that the inclined section of the conveyor belt can automatically adapt to the height change of the horizontal section of the conveyor belt. Since the horizontal section of the conveyor belt is close to the car, when the pigs walk on the conveyor belt, they first come into contact with the flat road, which can avoid the pigs from walking on the slope when leaving the car and feeling scared. This can reduce the fear and stress response of the pigs caused by walking on the slope, and enable the pigs to walk out of the car more quickly and smoothly, thus improving the unloading efficiency. The servo motor drives the active roller to rotate, thereby driving the conveyor belt to move. When the pigs walk on the conveyor belt, the conveyor belt can automatically transport the pigs from the car door to the unloading area, thus avoiding the phenomenon of pigs lingering and crowding when walking on the slope due to fear, further improving the unloading efficiency.

[0024] (2) By setting support components inside the conveyor belt, support plate one can support the horizontal section of the conveyor belt, and support plate two can support the inclined section of the conveyor belt. Support plate two is installed between the rotating shaft where the steering roller and the driven roller are located through a connecting ring. When the height of the steering roller changes, support plate two is always located on the line connecting the steering roller and the driven roller. Therefore, support plate two can always fit with the conveyor belt and provide stable support. It can bear the weight of the pigs transported on it and prevent the pigs from collapsing when walking on the conveyor belt. This makes the transport of pigs more stable and also protects the conveyor belt.

[0025] (3) By setting up a guide, when not in use, the lever is turned to a vertical position, at which point the lever closes the mounting frame, preventing the odorant particles from escaping when not in use, avoiding waste of odorant particles, and extending the service life of the odorant particles. When in use, rotating the lever opens the mounting frame, and rotating the lever also changes the direction of the air outlet, thus changing the direction of fragrance emission as needed. Then, the fan is turned on, blowing air onto the odorant particles in the partition plate and the air outlet plate, allowing the odorant particles to quickly disperse and permeate the conveyor belt. While the fan is rotating, it also drives the stirring plate to rotate, turning the odorant particles. Not only does it allow the odorant granules to release their fragrance evenly, but it also increases the gaps between the odorant granules, helping air circulation. This results in a stronger and wider-ranging fragrance, making it easier to attract pigs in the truck bed. This encourages pigs to voluntarily walk onto the conveyor belt, reducing the need to herd them. By changing the traditional passive unloading to active unloading, pigs can leave the truck bed more quickly, further improving unloading efficiency. It also significantly reduces stress reactions caused by herding, minimizing falls and abrasions, and preventing PSE (preferably soft, succulent, and seborrheic) meat, thus improving the appearance and quality of the pork.

[0026] (4) By setting up a dispersing device, when pigs pass through the area of ​​the conveyor belt and the transition plate, if the pigs are afraid and do not move, they will stay on the conveyor belt. At this time, the infrared sensor detects that the pigs are not moving or the number of pigs is increasing, and sends the detected signal to the processor. The processor controls the buzzer to make a sound. Since pigs have poor eyesight but sensitive hearing, the direction of the pigs is guided and the pigs that are staying are driven away, prompting the pigs to leave the conveyor belt and avoiding the pigs from staying and crowding together, thereby further improving the unloading efficiency.

[0027] (5) By setting a transition plate on the support block, one end of the transition plate is located above the conveyor belt. The transition plate can transition the height between the end of the conveyor belt and the mounting platform, reducing the pigs' fear and preventing them from staying due to fear.

[0028] (6) By filling the guide with odorant, pigs are very greedy animals and have a very sensitive sense of smell. By simulating the smell of food or the smell that pigs like, the pigs can be guided to leave the carriage on their own.

[0029] (7) By setting a rotatable cover, when the odorant granules become ineffective after long-term use, the cover can be opened by pulling the handle, the ineffective odorant granules can be poured out and new odorant granules can be added, and then the cover can be closed, making the replacement of odorant granules convenient and quick.

[0039] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0040] Example 1:

[0041] This invention provides a pig transport device for slaughterhouses. Please refer to [link / reference]. Figure 1-7 The system includes an installation platform 1 and casters 2 at the bottom of the installation platform 1. A lifting conveyor 3 is installed above the installation platform 1. The lifting conveyor 3 can be height-adjusted according to the height of the truck bed, maintaining alignment with the truck bed exit for easy unloading of pigs. The lifting conveyor 3 consists of a horizontal section and an inclined section of conveyor belt 309. The horizontal section of the conveyor belt 309 is close to the truck bed, preventing pigs from feeling afraid and allowing them to walk onto the conveyor belt 309 more actively and smoothly, thus improving unloading efficiency. The lifting conveyor 3 includes a hydraulic cylinder 301, a lifting platform 302, a support 303, a drive roller 304, a servo motor 305, a steering roller 306, a clamping roller 307, a driven roller 308, and a conveyor belt 309. Multiple hydraulic cylinders 301 are fixedly connected to the installation platform. On the mounting platform 1, the lifting platform 302 is fixedly connected to the output end of the hydraulic cylinder 301, and the bracket 303 is fixedly connected to the lifting platform 302. The bracket 303 is provided with two sets. The active roller 304 is rotatably connected between one set of brackets 303. The servo motor 305 is fixedly connected to the mounting platform 1. One end of the active roller 304 passes through the bracket 303 and is fixedly connected to the output shaft of the servo motor 305. The steering roller 306 and the clamping roller 307 are rotatably connected between the other set of brackets 303. The driven roller 308 is set on the mounting platform 1. The conveyor belt 309 is sleeved on the outside of the active roller 304, the driven roller 308 and the steering roller 306. The distance between the steering roller 306 and the clamping roller 307 is slightly greater than the thickness of the conveyor belt 309, and the conveyor belt 309 passes through the steering roller 306 and the clamping roller 307.

[0042] The lifting conveyor 3 also includes a slide rail 310, a slider 311, a support block 312, a baffle 313, and a spring 314. There are two slide rails 310 and they are fixedly connected to the mounting platform 1. The slider 311 is slidably connected to the slide rail 310. The support block 312 is fixedly connected to the top of the slider 311. The driven roller 308 is rotatably connected between the support blocks 312. The baffle 313 is fixedly connected to one end of the slide rail 310. The spring 314 is fixedly connected between the support block 312 and the baffle 313. A transition plate 4 is rotatably connected to the support block 312. One end of the transition plate 4 is located above the conveyor belt 309. The transition plate 4 can transition the height between the end of the conveyor belt 309 and the mounting platform 1, reducing the fear of pigs and preventing pigs from being stranded due to fear.

[0043] The hydraulic cylinder 301 drives the lifting platform 302 to move up and down, which in turn drives the drive roller 304, steering roller 306, clamping roller 307 and conveyor belt 309 to move up and down, keeping the conveyor belt 309 level with the exit of the car. At this time, the height of the horizontal section of the conveyor belt 309 changes, which will drive the slider 311 to slide in the slide rail 310, so that the inclined section of the conveyor belt 309 can automatically adapt to the height change of the horizontal section of the conveyor belt 309. Since the horizontal section of the conveyor belt 309 is close to the car, when the pigs walk on the conveyor belt 309, they first come into contact with the flat road, which can avoid the pigs being afraid of walking on the slope when leaving the car. This can reduce the fear and stress response of the pigs caused by walking on the slope, and enable the pigs to leave the car more quickly and smoothly, thus improving the unloading efficiency.

[0044] The servo motor 305 drives the active roller 304 to rotate, which in turn drives the conveyor belt 309 to move. When the pigs walk onto the conveyor belt 309, the conveyor belt 309 automatically transports the pigs from the door of the truck to the unloading area. This avoids the phenomenon of pigs being afraid and lingering or crowding when walking on the slope, thus further improving the unloading efficiency.

[0045] The conveyor belt 309 is internally equipped with a support member 5, which supports the conveyor belt 309 and bears the weight of the pigs being transported on it, preventing the pigs from collapsing while walking on the conveyor belt 309, making the pig transportation more stable, and also protecting the conveyor belt 309. The support member 5 includes a support frame 501, a first support plate 502, a connecting ring 503, and a second support plate 504; there are two support frames 501, which are symmetrically arranged on both sides of the conveyor belt 309. The support frames 501 are fixedly connected to the lifting platform 302, and the first support plate 502 is fixedly connected to the support frame. Between 501, the steering roller 306 and the driven roller 308 are both fixedly sleeved on the rotating shaft. The steering roller 306 and the driven roller 308 are rotatably connected to the bracket 303 and the support block 312 respectively through the rotating shaft. Two sets of connecting rings 503 are provided. The two sets of connecting rings 503 are rotatably sleeved on the outer wall of the rotating shaft where the steering roller 306 and the driven roller 308 are located. The second support plate 504 is fixedly connected to the connecting ring 503. The outer diameter of the connecting ring 503 is smaller than the outer diameter of the steering roller 306 and the driven roller 308. The first support plate 502 and the second support plate 504 are both located inside the conveyor belt 309.

[0046] Support plate 1 502 can support the horizontal section of the conveyor belt 309, and support plate 2 504 can support the inclined section of the conveyor belt 309. Support plate 2 504 is installed between the rotating shaft where the steering roller 306 and the driven roller 308 are located through the connecting ring 503. When the height of the steering roller 306 changes, support plate 2 504 is always located on the line connecting the steering roller 306 and the driven roller 308. Therefore, support plate 2 504 can always fit in close contact with the conveyor belt 309 and provide stable support.

[0047] A guardrail 6 is fixedly installed on the lifting platform 302, and a guardrail 7 is fixedly installed on the support plate 504. Both guardrails 6 and 7 are located on opposite sides of the conveyor belt 309. A guide 8 is installed on guardrail 6. The guide 8 emits a food or pig-pleasing aroma, filling the conveyor belt 309 with fragrance, thereby guiding the pigs to voluntarily walk onto the conveyor belt 309 and reducing the need to drive them. The guide 8 includes a mounting frame 801, a guide box 802, a partition plate 803, and an air vent plate 804. 4. Fan 805, reducer 806, stirring plate 807, mounting frame 808, lever 809, magnetic plate one 810, magnetic plate two 811, cover plate 812, and handle 813; mounting bracket 801 is hung on guardrail 6, guide box 802 is fixedly connected to the end of mounting bracket 801 near the inside of guardrail 6, partition plate 803 is fixedly connected to the inside of guide box 802, air outlet plate 804 is fixedly connected to the end of guide box 802 near guardrail 6, and fan 805 is installed in guide box 805. 02. At the end furthest from the guardrail 6 on the inside, power supply 1 is located inside guide box 802, switch 1 is located on top of guide box 802, fan 805 is electrically connected to power supply 1 via switch 1, reducer 806 is embedded and fixedly connected to partition plate 803, the central shaft of fan 805 is connected to the input end of reducer 806, the central shaft of stirring plate 807 is connected to the output end of reducer 806, mounting frame 808 is fixedly connected to the end of guide box 802 near conveyor belt 309, and dial... Several pieces 809 are provided and evenly distributed inside the mounting frame 808. The paddle 809 is connected to the mounting frame 808 with damping rotation. The top of the guide box 802 is provided with a feeding port. Magnetic piece 1 810 is fixedly connected to the end of the cover plate 812 away from the hinge. Magnetic piece 2 811 is fixedly connected to the side wall of the feeding port. Magnetic piece 1 810 and magnetic piece 2 811 attract each other on their adjacent sides. The cover plate 812 is rotatably connected to one end of the feeding port through a hinge. The handle 813 is fixedly connected to the top of the cover plate 812.

[0048] Both the partition plate 803 and the vent plate 804 are filter plates. The space between the partition plate 803 and the vent plate 804 is filled with odorant particles. The odorant is preferably a synthetic food flavoring agent. Pigs are very greedy animals and have a very sensitive sense of smell. By simulating food with food flavoring agents, pigs can be guided to leave the carriage on their own.

[0049] When not in use, the lever 809 is in a vertical position, closing the mounting frame 808 and preventing the odorant particles from escaping, thus avoiding waste and extending their lifespan. In use, rotating the lever 809 opens the mounting frame 808 and changes the direction of the airflow, allowing for customized fragrance distribution. Then, the fan 805 is turned on, blowing air onto the odorant particles within the partition plate 803 and the air outlet plate 804, quickly dispersing the fragrance across the conveyor belt 309. Simultaneously, the fan 805 rotates the stirring plate 807, agitating the odorant particles and ensuring even fragrance distribution, while also enhancing the aroma. The gaps between the odorant granules facilitate air circulation, resulting in a stronger and wider-ranging aroma that more easily attracts pigs in the truck bed. This encourages pigs to voluntarily walk onto the conveyor belt 309, reducing the need to herd them and transforming unloading from a passive to an active process. This not only improves unloading efficiency but also significantly reduces stress caused by herding, minimizing falls and abrasions. It also prevents PSE (partially spoiled) meat, improving the appearance and quality of the pork. When the odorant granules become ineffective after prolonged use, simply pull the handle 813 to open the cover 812, pour out the ineffective odorant granules, add new ones, and then close the cover 812. This makes odorant granule replacement convenient and quick.

[0050] The guardrail 2 7 is equipped with a dispersing component 9, which can automatically guide the pigs when they are clustered and stuck on the conveyor belt 309, drive the stuck pigs off the conveyor belt 309, and make unloading more efficient. The dispersing component 9 includes a mounting plate 901, an infrared sensor 902, a buzzer 903, a power supply 2, and a switch 2. The mounting plate 901 is fixedly connected to the guardrail 2 7. The infrared sensor 902 and the buzzer 903 are both installed on the side of the mounting plate 901 near the conveyor belt 309. The mounting plate 901 is equipped with a power supply 2 and a switch 2. The infrared sensor 902 and the buzzer 903 are electrically connected to the power supply 2 and the switch 2. The infrared sensor 902 is controlled and connected to the buzzer 903 through a processor.

[0051] When switch two is turned on, infrared sensor 902 and buzzer 903 start working. When pigs pass through the area between conveyor belt 309 and transition plate 4, if a pig is afraid and does not move, it will linger on conveyor belt 309. At this time, infrared sensor 902 detects that the pig is not moving or that the number of pigs has increased, and sends the detected signal to the processor. The processor controls buzzer 903 to make a sound. Since pigs have poor eyesight but sensitive hearing, the buzzer guides the pigs and drives away the lingering pigs, prompting them to leave conveyor belt 309 and preventing them from lingering and crowding together, thereby further improving unloading efficiency.

[0052] Working principle: After the truck carries the live pigs into the farm, it pushes the equipment to the exit of the truck bed, then starts the hydraulic cylinder 301 and the servo motor 305, and turns on switch one and switch two.

[0053] The hydraulic cylinder 301 drives the lifting platform 302 to move up and down, which in turn drives the drive roller 304, steering roller 306, clamping roller 307 and conveyor belt 309 to move up and down, keeping the conveyor belt 309 level with the exit of the car. At this time, the height of the horizontal section of the conveyor belt 309 changes, which will drive the slider 311 to slide in the slide rail 310, so that the inclined section of the conveyor belt 309 can automatically adapt to the height change of the horizontal section of the conveyor belt 309. Since the horizontal section of the conveyor belt 309 is close to the car, when the pigs walk on the conveyor belt 309, they first come into contact with the flat road, which can avoid the pigs being afraid of walking on the slope when leaving the car. This can reduce the fear and stress response of the pigs caused by walking on the slope, and enable the pigs to leave the car more quickly and smoothly, thus improving the unloading efficiency.

[0054] The servo motor 305 drives the active roller 304 to rotate, which in turn drives the conveyor belt 309 to move. When the pigs walk onto the conveyor belt 309, the conveyor belt 309 can automatically transport the pigs from the door of the truck to the unloading area, thereby avoiding the phenomenon of pigs being afraid and lingering or crowding when walking on the slope, and further improving the unloading efficiency.

[0055] When pigs are transported on conveyor belt 309, support plate 1 502 can support the horizontal section of conveyor belt 309, and support plate 2 504 can support the inclined section of conveyor belt 309. Support plate 2 504 is installed between the shaft where the steering roller 306 and the driven roller 308 are located through connecting ring 503. When the height of the steering roller 306 changes, support plate 2 504 is always located on the line connecting the steering roller 306 and the driven roller 308. Therefore, support plate 2 504 can always fit in close contact with conveyor belt 309 and provide stable support. It can bear the weight of the pigs transported on it and prevent the pigs from collapsing when walking on conveyor belt 309, making the transport of pigs more stable and protecting conveyor belt 309.

[0056] When not in use, the lever 809 is in a vertical position, closing the mounting frame 808 and preventing the odorant particles from escaping, thus avoiding waste and extending their lifespan. In use, rotating the lever 809 opens the mounting frame 808 and changes the direction of the airflow, allowing for customized fragrance distribution. Then, the fan 805 is turned on, blowing air onto the odorant particles within the partition plate 803 and the air outlet plate 804, quickly dispersing the fragrance across the conveyor belt 309. Simultaneously, the fan 805 rotates the stirring plate 807, further dispersing the odorant particles. The odorant granules are turned over, which not only allows the odorant granules to release their aroma evenly, but also increases the gaps between the odorant granules, helping air circulation. This makes the aroma stronger and spreads over a wider area, making it easier to attract the pigs in the truck. This encourages the pigs to walk onto the conveyor belt 309 more actively, reducing the need to drive the pigs. This changes the unloading process from passive to active, allowing the pigs to get out of the truck more quickly and improving unloading efficiency. It also greatly reduces the stress response caused by driving the pigs, reducing the risk of them falling and getting abrasions. At the same time, it also avoids PSE meat, improving the appearance and quality of the pork.

[0057] When the odorant granules become ineffective after prolonged use, the cover plate 812 can be opened by pulling the handle 813, the ineffective odorant granules can be poured out and new odorant granules can be added, and then the cover plate 812 can be closed again, making the replacement of odorant granules convenient and quick.

[0058] After switching on switch 2, infrared sensor 902 and buzzer 903 are activated. When pigs pass through the area between conveyor belt 309 and transition plate 4, if a pig is afraid and does not move, it will linger on conveyor belt 309. At this time, infrared sensor 902 detects that the pig is not moving or that the number of pigs has increased, and sends the detected signal to the processor. The processor controls buzzer 903 to make a sound. Since pigs have poor eyesight but sensitive hearing, the buzzer guides the pigs and drives away the lingering pigs, prompting them to leave conveyor belt 309. This avoids pigs lingering and crowding together, thereby further improving unloading efficiency.
